The Bentley Turbo RT Mulliner: The Mulliner version, available only by special order for the 1998 model year, was even more exclusive and expensive.[10] It boasts a 420 bhp (313 kW; 426 PS) engine with a torque output of 634 lbft (861 Nm): this was achieved by developing a new compressor for the turbocharger, remapped engine management system, and modifications to the air intake system. Visually, Mulliners have more aerodynamic, rounded bumpers with prominent venting and often foglamps, as well as flared fenders to accommodate a wider track and larger 18-inch alloy wheels, sitting on low-profile 255/55 tires. Each car was built to individual specifications, with many sporting side and bonnet vents and also the smaller Mulliner rear windscreen. One popular feature in Mulliners is a prominent speedometer for the rear passengers.
Just 56 Mulliner editions were built, of which 17 are right-hand drive. Seven of the Mulliner editions built are to standard wheelbase specifications, and 49 are on the lengthened wheelbase.
